On a note parallel to the NHS attitude to thyroid disease and treatment, we now find that the advice of not weaning babies until 6 months of age has caused an outbreak of allergies. This has been recognised elsewhere in the world, but the dear old NHS simply doesn't change its fatal directions. It's the same I fear with changes to thyroid treatment practice. The sheer arrogance, mediocrity and intransigence of the NHS and its advisors really is an indictment of their attitudes of "knowing best in spite of any evidence to the contrary from elsewhere, however well devised". One has to wonder why new thinking and action so often has to come from elsewhere before it is slowly accepted in the UK.
